Fort Pitt Tunnel
From Wikipedia, the free encyclopedia
The Fort Pitt Tunnel carries I-279 between Green Tree, Pennsylvania and downtown Pittsburgh. It has two lanes both inbound and outbound. The tunnel travels beneath Mount Washington. Its northern ramps lead directly to the Fort Pitt Bridge which is a double-deck bridge. To mesh with the bridge, the north portal has openings at two levels, with the eastern opening leading to the top deck of the bridge. At the south portal the openings are at the same level.
Entering the tunnel, you see a dull view of Mount Washington, but when you exit you see a spectacular view of Pittsburgh's skyline, often famous as "the best way to enter an American city". The view was also the inspiration for the news open on CBS affiliate KDKA-TV for several years in the 1980's and 1990's. [1] It is referenced in the novel The Perks of Being a Wallflower, by Stephen Chbosky.
